The variables such as mass flow of pulverized coal flow out of the mill, mass of coal rejected by classifier etc. which is not measurable in the power plant can be obtained from the model. Fig. 3. Variation of mass flow of raw coal and primary air flow with time.
Raw mill exhaust fans are operated with very adverse situations because the fan handles mainly gases such as CO2, N2, NOx and Sox along with some dust particles. Coal mill fans: In cement industry coal mill fans are used to supply required air for burning coal and remove the exhaust gases produced after burning.
